Manchester United without injured Nemanja Vidic for San Siro showdown against Milan

Nemanja Vidic was again missing as Manchester United resumed their quest toreach a third consecutive Champions League final.

Ruled out: Vidic will not face AC Milan at the San Siro

Sir Alex Ferguson's men flew out Italy this morning for Tuesday's encounter with an AC Milan side featuring former player David Beckham.

Vidic, who has yet to play in 2010 after developing a nerve problem in his leg, was ruled out, leaving Ferguson to decide whether Jonny Evans or Wes Brown should partner new England skipper Rio Ferdinand in central defence.

Ryan Giggs is also missing after breaking an arm in last week's draw at Aston Villa, but the remainder of United's first-team squad, with the exception of out-of-favour midfielder Anderson, made the two-hour trip for a meeting with the seven-time winners who have beaten United on all four occasions they have met in a two-legged European tie.
